The benefits of cruise control systems are well known: automating the often tedious job of maintaining steady driving speeds while delivering the side benefit of better fuel efficiency.  However, sustaining optimum speeds is not always easy during times of heavy traffic when cars around you may be traveling at varying speeds, and especially in bumper-to-bumper traffic.

Aiming to remedy this is Cadillac with its ‘Super Cruise’ semi-autonomous technology that’s capable of fully automatic steering, braking, and lane-centering in highway driving. The automaker is road testing this technology now.

Key to delivering this semi-autonomous capability is the integration of lane-centering technology that uses forward-looking cameras to detect lane markings, along with GPS map data to detect curves and other road characteristics. Already, many of the building block technologies for Super Cruise are available as part of the available Driver Assist Package on Cadillac’s 2013 XTS and ATS models.

The system uses sensor fusion to provide 360 degrees of crash risk detection and enhanced driver assist features like rear automatic braking, intelligent brake assist, range adaptive cruise control, lane departure warning, and more. Cadillac says the system could be ready for production vehicles by mid-decade.
